1. General description
The 74AHC241 and 74AHCT241 are 8-bit buffer/line drivers with 3-state outputs. These
devices can be used as two 4-bit buffers or one 8-bit buffer. They feature two output
enables (1
OE and 2OE), each controlling four of the 3-state outputs. A HIGH on 1OE or
LOW on 2OE causes the associated outputs to assume a high-impedance OFF-state.
Inputs are over voltage tolerant. This feature allows the use of these devices as
translators in mixed voltage environments.
2. Features
Balanced propagation delays
All inputs have a Schmitt-trigger action
Inputs accepts voltages higher than V
CC
For 74AHC241 only: operates with CMOS input levels
